Currently I've got a cheap M to E adapter, and put a Leica 35/2 lens on the A7, but I'm looking for something wider, while leaving the 35 on an MM. The focus seems off sometimes, which I think is due to the quality of the adapter (e.g. I focus, and the adapter moves a little, putting the focus out).

So, I'm looking for a 24 or 25mm lens to shoot on the A7s. It can be an M lens, and I'll get a better adapter (so I could use it on the M if needed) or another mount completely with adapter. I want to stick with Manual focus lenses (and ones designed to be) and my budget is about £500 total (adapter+lens).

if f2.8 is alright for you than imo the OM 2.8/24 is the best choice. and better get the later version that has multi coating, it either says MC or Zuiko 'only', not the single coated 'H-Zuiko"
the Pentax K is very good too, has the more sturdy build might even have the better coating, but corner performance, if this is of importance, is a bit weaker and it's a bit heavier and bigger.
Rokkor 2.8/24 is another favourite, great lens, the Nikkor 2.8/24 is also very good, both a bit bigger again, the later has great colours ( but that could be personal ) but the most distortion.
If talking f2 there also is the fantastic Pentax f2/28, optically identical to the 2/28 Distagon but smaller, lighter and much cheaper
Of the mentioned f2 I don't have personal experience, of the f2.8 I do. Of course there also is the Distagon, and I read that the Konica AR 2.8/24 is very good too.

right! not cheap, cheaper is relative to the Zeiss only
and..I am just at a marriage party and drunk..so the 28mm came in, sorry for that. I hope that my other infos are right though ( will check again tomorrow ) )
the CV 4/25 is very good, but the corners on any A7 camera aren't, any SLR lens fares better

So when you're all talking about corner performance, is this only with regards to colour shifting? I perhaps should have mentioned that I shoot exclusively in B&W. Does that basically mean I can ignore lack of 'corner performance' in any lens selections?

Most adapted rangefinder wides get kinda smeary, i.e., blurry in the corners, on mirrorless cameras. They're not accustomed to the thick glass that covers digital sensors. The A7s is purportedly the best of the bunch for this, though (with the exception of the Leica Ms of course). If you're not fussy about corner performance, an M-mount wide will work fine, especially in B&W. SLR wides were designed with the rear element further away from the film plane, though, resulting in less oblique rays of light to the corners, and so generally do better penetrating the sensor cover glass.

I've also owned the CV25mm LTM and used it on the M9 couple of years ago and found it to be a decent performer, regret selling this lens to be honest as it didnt exhibit any color shift or soft corners so it might be a decent light performer on the A7sTest shot with Snapshot Skopar 25mm by Earl Dieta, on FlickrL1002512 by Earl Dieta, on Flickr

1: thank's a lot! by now more drunk again, but I just left the party and hopefully I'm not too drunk and will write nonsense
2: no, there also is loss of sharpness usually referred to as 'smearing'. might not disturb for the majority of photos, but...for some it will ( link to my pics taken with the CV 4/25, the first some 30 seen on Sony A7, below )
3: since it only says 'Zuiko', even though Sebastian says it's not, I am rather sure that the f2/24 you linked must be multicoated. I believe that he got the serial numbers confused wit those of the f2.8 version ( ha, not all that drunk! )
according to this very good Olympus source, but in German, there actually isn't any single coated but only multi coated versions of the f2/24mm: http://olypedia.de/Zuiko_Auto-W_1:2/24_mm (phhu, good I found out, I have a OM 2/28 I haven't seen but had bought waiting for me back in Austria )

Kuuan, the link in your sig doesn't work for me. Here's one to Kuuan's sample images that should work for anyone:

ohhhh, my links didn't work! thank you VERY much for that Sebastian!! and happy that you find my samples useful
just corrected that and put the links in a crude but hopefully working form.

at the link you provided that leads to all my 'albums' of manual lenses, in order from wide to long, and photos taken with them, samples of the mentioned 2.8/24 lenses can be seen. However most had been taken on APS-C sensor cameras, only the first 24 photos seen ( 24 right now, soon it will be more, incl. some of tonights party ) in the album of the OM 2.8/24 were taken on FF Sony A7: https://www.flickr.com/photos/kuuan/...7633627307747/

in comparison the 'album' with the photos taken with the CV 4/25 you are interested in. Right now about the first 30 seen had been taken on FF Sony A7, the rest on APS-C ( the first one taken on APS-C is the mirrorimage showing my hand and a 'tube' ): https://www.flickr.com/photos/kuuan/...7633352494287/

Just one more thought: The OM 24mm f/2.8 is a good lens, but I don't know that it's that much better than other SLR lenses, except for being smaller.

according to my own tests but performed on APS-C sensor, and according to the test at 16-9 linked above on Canon FF it most likely is.
if wanted an f2 I read ( don't have the lens ) that's not too expensive but said to be very good Canon comes in

One final question: Kuuan, or anyone else, do you have a suggested adapter to go from OM to E?

Just going to buy the lens now.

Peter

hm..I may be the wrong person to ask as I am sure that others would warn against this. I have read reports again and again that it 'also' happened that an adapter from a more expensive brand had been worse than a cheap one. My strategy therefore has been to just to buy the cheapest one I could find from China on ebay and if it's not good enough to simply buy a different one. That have been some 20+ different adapters in total for Sony E, Leica M and Pentax K mounts. I have been happy with all of them but two, a Pen-F>E mount adapter which only fit some but not all lenses, and that, as I had to find out, was because the Pen-F lenses have, most surprisingly, two variations of bajonets, and a Leica M>E mount adapter, the only one which was not just the cheapest but from a bit reputed brand, which simply was too tight.

can't recommend the seller I had bought my OM>E mount adapter from because right now he isn't offering any

Just to confirm, Kuuan was right about the Fordes lens. It's an f/2 and it is multi-coated.

Adapters: If you want to scale-focus, you'll want one that's quite precise. In any case, you want one that will reach to infinity. I never scale-focus, so I have been using cheap adapters with good success.

I don't think anyone has mentioned the Voigtlander 25. If have the first version and used it for the brief time I had an A7. It's not RF coupled but focuses on the Sonys.

The thing I like about it, and the reason I have kept it, is because of the focus click stops at 1m, 1.5m and 3m for working hyperfocally. Love that feature.

I shoot all BW, so wasn't concerned about color shift, if there even was any. It's also tiny and has a focus tab.

John Peter had specifically asked about this lens in his original query and there had been mention of it a few times and I linked to my photos I had taken with it:

I have been defending this lens for use on an A7 but many don't agree and therefore I have become hesitant to recommend it. Corners are critical but it really depends on personal use and views, I think best for anyone is to view samples and see for himself

Kuuan, I am jealous of all the color in your locations! Very nice shots in these sample albums.
Thank you for the samples.

thank you for the thumbs up Colonel These had been taken in the colourful places Bali and Vietnam with lot's of sun. - which actually makes the use of old lenses, which I like, a bit tricky at times but the CV, being a rather modern lens is doing great and in this respect has an advantage over the OM. I feel a bit guilty of not having recommended the CV, it really is a fantastic lens and as I had written earlier about the colour shift resp. corner problematic: "there also is loss of sharpness usually referred to as 'smearing'. might not disturb for the majority of photos, but...for some it will". Good corners are the biggest advantage of the OM and it's up for the user to decide which factors are decisive for him.

Lens and adapter arrived yesterday. Seems good, need to get used to focusing with it, but shouldn't take to long.

Hopefully soon I'll do some documentary stuff with it, I'm due to spend a day in a train cab with a driver, so will be better than a 35mm for the cramped conditions, but for now here are four from a quick walk around Oxford this morning:
